Image rendering issues - pink around plants in vector views

[VegasDave]

Thank you Leanne!! For me, your solution worked perfectly. I've never cared about the 'pink halo' while in vector view (and it didn't show up in full render, so why worry about it), but this does make for a much cleaner 'look' during all phases of viewing plans.
Thanks so much for resolving this issue, at least for my personal computer - sure hopes it works as well for all others.

Yes, let me chime in on the thank you also. Even though I have a newer computer, the pink halo has been with me since XP on a 5 yr old computer and with Vista; which is on a year old computer. So your fix does exactly what was needed.
